Fermented apple juice containing approximately 5-6% acetic acid. Limited evidence suggests modest benefits for blood glucose regulation after meals. Most popular claims lack strong clinical support.
May modestly reduce postprandial blood glucose
MODERATEAcetic acid inhibits disaccharidase enzymes in the brush border and delays gastric emptying, slowing carbohydrate absorption
May slightly enhance satiety and reduce calorie intake
LIMITEDDelayed gastric emptying and mild nausea may reduce appetite, though this is not a reliable mechanism for weight loss
COMMON: 15-30 mL
TIMING: Diluted in water before or with meals
Always dilute in water to protect tooth enamel and esophageal tissue. Undiluted ACV can cause chemical burns. Capsule forms vary widely in actual acetic acid content.
